Watch as Dylan Lentini has an outburst during court and is taken away.

After a delay, Lentini was brought back and given his sentence.

Lentini was convicted in September of stabbing 66-year-old Michael Wimbert nearly three dozen times last year in his apartment in West Nyack.

Lentini claimed he stabbed Wimbert while fighting off a sexual assault who was defending himself. A jury convicted him of second-degree murder.

Police said Wimbert had posted an ad for a roommate on Craigslist. The suspect answered the ad and made arrangements with Wimbert to be picked up from the train station in White Plains on Nov. 27.

Prior to the ad being answered, there was no relationship between the two men, police said.

Following the outbursts, a calmer Lentini addressed the crowd before sentencing. In a rambling and often disjointed statement, he maintained his innocence.

The Rockland County Prosecutor said justice was served.

"The overwhelming evidence in this case established that the defendant did not act in self-defense when he stabbed his victim over 30 times, several times in the back," said Prosecutor Thomas Zugibe. "Instead they found him to be a cold-blooded killer."
